Inside Locker

Everything Locker does, from catching the first idea to delivering the final master, with Kii keeping it all organised in between.

Kii, your AI

The intelligence layer over your whole catalogue.

Catalogue assistant

Ask Kii anything about your music and get a straight answer: counts, gaps, what you've got at a given tempo or key. It can take action too, across dozens of tasks.

Auto-organise

Drop in a folder of bounces and Kii sorts them into songs, versions and stems. Named, tagged and credited, the way you'd do it by hand.

Knowledge Hub

Kii learns your catalogue from your files and sources, fills in missing credits and splits, and surfaces suggestions for you to approve. It never changes your data silently.

Write & capture

Catch ideas the moment they land.

Voice notes

Record an idea on the spot, get it transcribed automatically, and pin it to the exact lyric section it belongs to.

Lyrics editor

Write and structure lyrics with proper sections, kept versioned and tied to the track they belong to.

Rhyme & thesaurus

Built-in rhyme and thesaurus tools that put the words worth singing first: more singable and usable, not just the most common.

Organise

Your whole catalogue, in order.

Track management

Store tracks with metadata, artwork, linked files and full version history.

Versions & A/B compare

Keep every version of a track together and compare mixes side by side.

Stems

Upload stem packs and Locker detects them and links them to the right song automatically.

Audio analysis

Automatic BPM, key, genre, mood and instrument detection, plus waveforms, on every track.

Smart search

Find anything fast with filters for BPM, key, mood, creators, tags and more.

Find similar

Surface tracks that actually sound alike using audio fingerprints. Handy for references and playlisting.

Playlists & projects

Group tracks into playlists and project pages to keep sessions and releases organised.

Credits & history

Know who did what, and undo anything.

Splits & credits

Track writer and producer credits and splits properly, with even-split and per-row editing, and Kii keeps them tidy.

Contacts & collaborators

A contact book of everyone you work with, linked to the songs they're on.

History & undo

Every change is logged in plain English and can be undone, including the things you let Kii do.

Share & deliver

Get your music out, properly.

Smart share links

Send tracks, playlists, lyrics or whole folders as a polished, dark-mode-ready page. Each link is a snapshot you can edit later.

Client Zones

Give clients a private listening room of their own, with secure email-code access, not a raw link anyone can forward.

Share Insights

See who opened a share, what they listened to, and what they downloaded, across every track, playlist and project.

Comments & approvals

Feedback and approvals stay attached to the work instead of scattered across email and chat.

Folder & team shares

Share whole folders and invite collaborators with fine-grained permissions that cascade to everything inside.

Security & access

Your unreleased music, protected.

Encrypted storage & transfer

Files are encrypted at rest and in transit between Locker and your browser.

Access controls

Fine-grained permissions for who can view, edit, download or share.

Cloud storage

Your library, available across every device, without relying on scattered local folders.

Mobile & iOS

Reach your whole catalogue from your phone, including the native iOS app.
